This tropical perennial, belonging to the Phyllanthaceae family, is native to Southeast Asia and is cherished in its variegated form for its compact habit and beautifully patterned foliage.

Small yet captivating, Phyllanthus urinaria ‘Compacta Variegata’ is an unusual choice for collectors seeking a distinctive foliage plant with cultural heritage and visual elegance.

Phyllanthus urinaria ‘Compacta Variegata’ – Care Guide

Light

Thrives in bright, indirect light. Ample filtered light maintains its variegation and compact growth. Avoid harsh direct sunlight, which may scorch the delicate variegated leaves, and low-light conditions, which can lead to fading colours and leggy stems.

Watering

Keep the soil consistently moist but not waterlogged. Water when the top 2–3 cm of soil feels dry to the touch. This species prefers even hydration, especially during warm months. In winter, allow the soil to dry slightly more between waterings. Always ensure good drainage to prevent root rot.

Temperature and Humidity

Temperature: Prefers warmth between 20–30 °C. Avoid cold drafts or temperatures below 15 °C.
Humidity: Moderate to high humidity (50–80%) helps maintain leaf vibrancy. Mist occasionally or use a humidifier if growing indoors in dry air.

Soil and Potting

Use a light, well-draining potting mix rich in organic matter. A blend of compost, perlite, and coco coir works well to retain gentle moisture while allowing airflow. Repot every 1–2 years in spring to refresh the soil and prevent compaction.

Feeding

Feed every 4–6 weeks during spring and summer with a diluted, balanced liquid fertiliser. Avoid over-fertilising, which can cause leaf burn or disrupt the variegation. Suspend feeding during autumn and winter.

Pruning and Maintenance

Pinch back new growth tips to encourage bushier, compact development. Remove yellow or damaged leaves regularly to maintain a tidy appearance. Wipe the leaves gently with a soft cloth to remove dust and showcase the delicate variegation.

Growth and Maturity

A compact and relatively fast-growing species, Phyllanthus urinaria ‘Compacta Variegata’ typically reaches 20–30 cm in height and width. Over time, it forms a dense mound of finely divided, variegated foliage — perfect for terrariums, shelves, or as a tabletop accent.

Common Issues

• Leaf drop: Caused by overwatering, sudden cold, or underwatering.

• Faded variegation: Insufficient light.

• Brown leaf tips: Low humidity or inconsistent watering.

• Pests: Occasionally affected by aphids or mealybugs — treat with neem oil or insecticidal soap.

Background and Benefits

Native to tropical Asia, Phyllanthus urinaria is known in traditional herbal medicine for its beneficial properties, often called the “Stonebreaker” plant for its historical use in kidney and liver remedies. The ‘Compacta Variegata’ form, however, is cultivated primarily for ornamental purposes due to its compact size and unique leaf variegation.

Symbolically, the plant represents endurance and harmony — thriving in warm, balanced conditions. Its refined form and calming tones make it ideal for small-space gardening, terrariums, and tropical-themed interiors.
